Talus
|
FHL tendon goes through groove btw posterior tubercles; blood vessels enter around neck.
|
|
Talus fracture
|
common injury from forced dorsiflexion (MVA). Fracture of neck can lead to AVN, death of talus.
|
|
Sustentaculum Tali
|
supports head of talus; tendon of FHL passes beneath
|
|
Calcaneal Fracture
|
often hurt due to high axial load on rear foot (jumping, falling). Must rule out associated fracture of lower spine. Injury involving STJ has poor prognosis, often leads to severe arthritis.
|
|
Metatarsal Fractures
|
Kicking, dropping something on foot. 5th commonly fractured, where Fibularis Brevis tendon inserts.
|
|
Plantar Aponeurosis
|
protects neurovascular structures of foot, supports longitudinal arch, helps compartmentalize foot.
|
|
Posterior Tibial Nerve
|
splits into Medial and Lateral Plantar Nerves
|
|
Medial Plantar Nerve innervates
|
4 intrinsic foot muscles: FDB, Abductor Hallucis, FHB, 1st medial lumbrical
|
|
Lateral Plantar Nerve innervates
|
all other intrinsic muscles of foot
|
|
Medial Plantar Nerve sensory
|
medial dorsum of foot and medial 3.5 toes
|
|
Lateral Plantar Nerve sensory
|
lateral dorsum of foot and 1.5 toes
|
|
Tarsal Tunnel
|
passage beneath flexor retinaculum for: Tendons of Tibialis Posterior and Flexor Digitorum Longus; Posterior Tibial Artery and Nerve; Tendon of Flexor Hallucis Longus.
|
|
Posterior Tibial Artery
|
divides into Medial Plantar Artery and Lateral Plantar Artery
|
|
Medial Plantar Artery
|
has superficial and deep branches; supplies mainly muscles of big toe
|
|
Deep Plantar Arch
|
formed from lateral plantar and deep plantar artery (from dorsalis pedis), uniting blood supply of plantar and dorsal surfaces. gives off metatarsal arteries and digital branches.
|
|
Diabetic Foot Ulcers
|
neuropathy causes loss of cutaneous sensation to plantar foot.
|
|
Subtalar Joint
|
plane synovial joint btw talus/calcaneous. Permits inversion and eversion during gait cycle. stabilized by interosseous talocalcaneal ligament.
|
|
Transverse Tarsal Joint
|
made up of 2 joints: calcaneocuboid and Talonavicular. same function as STJ.
|
|
Calcaneonavicular Ligament
|
spring ligament from sustenaculum tail to navicular. Has lots of elastic. Helps support longitudinal arch.
